Coming Up on 'This Week': Two Powerhouse Roundtables

NEW YORK, Dec, 7, 2012 — -- Two powerhouse roundtables of elected officials and political experts debate the latest on the stalemate over the fiscal cliff, Sunday on "This Week."

After another week of negotiations failed to produce any results, is the country moving closer to going over the fiscal cliff? With President Obama and House Speaker John Boehner, R-Ohio, holding firm on their positions on tax cuts for the wealthy, can anything lead to a breakthrough before the end of the year? And has debate over the debt ceiling become the major sticking point in deadlocked talks?

Sen. Tom Coburn, R-Okla.; Sen. Debbie Stabenow, D-Mich.; Rep. Jeb Hensarling, R-Texas; and Rep. Raúl M. Grijalva, D-Ariz., face off on the stalled fiscal cliff negotiations, this Sunday on "This Week."

Plus, George Stephanopoulos and the powerhouse roundtable debate all the week's politics, with political odd couple James Carville and Mary Matalin, Nobel Prize-winning economist and New York Times columnist Paul Krugman, and ABC News' George Will and Matthew Dowd.

With negotiations stalled, who will face the most blame in Washington if no deal is reached to avert the fiscal cliff? With 2016 speculation already beginning, are potential GOP hopefuls attempting to reboot the Republican Party's image in the wake of their presidential election loss? And as South Carolina Sen. Jim DeMint resigns from the Senate, what is the Tea Party's future in Washington? The powerhouse roundtable debates those topics and more, Sunday on "This Week."
